Next section: μ₁ -μ₂, independent groups, σ estimated

Summary of Computations

1. Specify the null hypothesis and an alternative hypothesis.
   
   
2. Compute M = Σ X/N.
   
   
3. Compute
   
   
4. Compute .
   
   
5. Compute where μ is the hypothesized value of the population mean.
   
   
6. Compute df = N -1.
   
   
7. Use a t table to compute p from t and df.

Assumptions

1. Normal distribution
   
   
2. Scores are independent
